A purchase order can be accepted by sales while engineering, production, quality and logistics are still working from different assumptions. The buyer thinks the product, packaging, tests and ship date are fixed; the supplier may see only a quantity, price and request to start.
A useful China purchase order creates a shared execution baseline before deposit, material purchasing or production. UN/CEFACT defines a purchase order as a message specifying goods or services ordered under conditions agreed between buyer and seller. The practical control is to make those conditions identifiable, measurable and changeable only through a recorded process.
1. Identify the order and legal parties
Record the PO number, issue date, buyer and seller legal names, addresses, contacts and notice emails. Link the quotation, pro forma invoice and project number. Pause when a beneficiary account, entity or address differs from the evidence already verified.
2. Tie every line item to one product baseline
For each SKU, state buyer and supplier part numbers, description, quantity, unit, unit price and currency. Reference the effective specification, drawing, BOM, colour standard, artwork, packaging revision and approved-sample number. “Same as last order” is not a revision. If the baseline is incomplete, use the product specification sheet guide first.
3. Reconcile quantity, tolerance and total price
Confirm whether over- or under-delivery is allowed, whether spare units are free, and which tooling, testing, packaging, labels, documents, bank charges or transport costs are included. Recalculate tier prices, discounts and the order total.
4. Convert payment language into verifiable events
State currency, beneficiary account and receipt condition. Define whether the balance becomes due after inspection approval, before loading, after receipt of copy shipping documents or another measurable event. Independently verify any account change.
5. State the Incoterms rule, named place and version
ICC Incoterms® rules allocate tasks, costs and risks around a named delivery point. Write the rule, place or port and version, such as “FOB Shanghai, Incoterms® 2020,” rather than FOB or DDP alone. Then separately confirm expected completion, booking party, cut-off, split shipments and consignee details. Compare boundaries in the FOB, EXW and DDP guide.
6. Freeze packaging, labels and shipping marks
Reference the unit pack, inner and master cartons, pallets, protection, pack quantity, dimensions, weights, barcode, labels and approved artwork. The U.S. International Trade Administration notes that packing-list and commercial-invoice information should align, so assign ownership for final packing data and document review.
7. Make quality acceptance a separate release gate
Reference the inspection checklist, critical characteristics, defect classes, test methods, sampling plan and release authority. An approved sample is a comparison baseline, not acceptance of the whole lot. Use the pre-production sample approval process to connect the evidence.
8. Assign compliance and document responsibilities
List only the reports, declarations, certificates, origin documents, invoice, packing list and transport documents that apply to the product and destination. Name the owner, due date and recipient. Do not copy a universal certificate list from another product or market.
9. Require an order response and define precedence
The supplier should confirm the PO and identify rejected, conditional or unclear terms. Agree which document controls if the contract, PO, pro forma invoice, specification, drawing, sample or email conflicts. Legal effect is transaction-specific, so this checklist does not replace contract advice.
10. Control every change
Use a revised PO or change record for quantity, price, product revision, material, process, site, schedule, packaging or payment. State old and new values, reason, affected stock, impact, approvers and effective orders. UN/CEFACT treats order, order change and order response as distinct information processes.
A one-page pre-production release checklist
- PO identity and legal parties verified.
- SKU, quantity, unit, price and currency reconciled.
- Specification, drawing, BOM, artwork and approved sample revisions aligned.
- Order total, extra charges, beneficiary and payment triggers confirmed.
- Incoterms rule, named place, version and delivery milestones complete.
- Packaging, labels, dimensions, weights and document owners assigned.
- Inspection criteria, sampling, defects and release authority approved.
- Applicable compliance evidence has an owner and due date.
- Order response, document precedence and open conditions recorded.
- Change, delay, failure and reinspection paths agreed.
Conclusion: resolve conflicts before starting cost
A good PO does not win by having more fields. It works when purchasing, engineering, production, quality, logistics, finance and the supplier are executing the same product version, delivery boundary and acceptance criteria.
Do not release production because a PO exists. Release it when the order has one confirmed baseline and every remaining condition has an owner and due date.
Frequently asked questions
Can a Chinese supplier start production as soon as I send a PO?
Not safely by default. First obtain a documented order response confirming the product baseline, commercial terms, delivery point, acceptance criteria, documents and open conditions.
Does a purchase order replace a supply contract or pro forma invoice?
Not automatically. The legal effect depends on the transaction and applicable law. Define which document prevails if the contract, PO, pro forma invoice, specification or drawing conflicts.
Is writing FOB on the PO enough?
No. State the rule, named port or place and version, for example FOB Shanghai, Incoterms 2020, then separately confirm booking, cut-off and document responsibilities.
